The Traditional Work Queue is a type of work queue that uses a number of worker threads that watch a queue and pick up an operation to process whenever one becomes available.
The traditional work queue is a FIFO queue serviced by a fixed number of worker threads. This fixed number of threads can be changed on the fly, with the change taking effect as soon as it is made. You can limit the size of the work queue to a specified number of operations. When this many operations are in the queue, waiting to be picked up by threads, any new requests are rejected with an error message.
The Traditional Work Queue component inherits from the Work Queue

Default Value | The work queue does not impose any limit on the number of operations that can be enqueued at any one time. |
Allowed Values | An integer value. Lower value is 0. Upper value is 2147483647 . |
Multi-valued | No |
Required | No |
Admin Action Required | Restart the server |
Advanced Property | No |
Read-only | No |
Description | Specifies the number of worker threads to be used for processing operations placed in the queue. If the value is increased, the additional worker threads are created immediately. If the value is reduced, the appropriate number of threads are destroyed as operations complete processing. |
Default Value | Let the server decide. |
Allowed Values | An integer value. Lower value is 1. Upper value is 2147483647 . |
